In case of recidivism, the recidivism ratio applies if it is higher than the offence category's ratio (first-time: 2/3, second-time: 3/4). The recidivism increase cap (Art. 108/2) is not included in this calculation.

Legal Basis

Conditional release ratios are set under Article 107 of Law No. 5275 on the Enforcement of Sentences and Security Measures: as a general rule, half (1/2) of a fixed-term sentence must be served; two-thirds (2/3) applies to intentional killing, torture, certain offences against sexual inviolability, offences against private life, and offences committed within organised crime activity; under Article 17 of the Anti-Terror Law No. 3713 and Article 108/9 of Law No. 5275, this ratio rises to three-quarters (3/4) for terrorism offences and for aggravated sexual assault, sexual abuse of children, and drug manufacturing/trafficking offences. For aggravated life and life imprisonment, a fixed term applies instead of a ratio (30 and 24 years respectively under the general rule; 36 and 30 years for organised-crime offences).

Under the enforcement regime for repeat offenders (Law No. 5275, Art. 108), the conditional release ratio for fixed-term sentences is two-thirds (2/3) on a first recidivism and three-quarters (3/4) on a second recidivism. This tool uses a simplified approach that applies whichever ratio is higher — the recidivism ratio or the offence category's ratio — and does not account for the Art. 108/2 cap under which the extra period added for recidivism may not exceed the heaviest of the sentences underlying the recidivism.

Under Article 99 of Law No. 5275, each sentence imposed on a person is independent of the others and retains its own legal existence; where multiple final judgments exist, an aggregation (içtima) decision must be requested from the enforcement judgeship to calculate the conditional release period. Aggregation is not a merger into a single sentence but a purely mathematical enforcement act: each sentence is calculated under its own enforcement regime and the resulting periods are then added together (Court of Cassation General Assembly of Criminal Chambers, File No. 2009/202, Decision No. 2009/234).

Under Article 61/6 of Turkish Criminal Code No. 5237, the length of a prison sentence is determined in days, months, and years; one day is 24 hours, one month is 30 days, and a year is calculated according to the official calendar (leap years also count as one calendar year).

Under Article 63 of Law No. 5237, all periods restricting personal liberty prior to the finalisation of the judgment — such as police custody or pre-trial detention — are credited against (deducted from) the imposed prison sentence.
